Rose plant named Poullow Yellow Hit

ABSTRACT

A new bright yellow miniature rose variety.

The present invention relates to a new and distinct variety of rose plant of the miniature rose class, which was originated by my crossing as seed and pollen parents, unpatented, unnamed seedlings of my creation. The denomination of this new rose is "Poullow Yellow Hit".

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive bright yellow flowers that hold color well attractively displayed on plants that grow well in pots. Asexual reproduction by budding of the new variety as performed in Fredensborg, Denmark, shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new variety, with color terminology in accordance with the Royal Horticultural Society Colour Chart (RHSCC). The terminology used in color description herein refers to plate numbers in the aforementioned color chart, e.g., "15C" is plate 15C of the Royal Horticultural Society Colour Chart.

Seed parent.--My unpatented, unreleased, unnamed seedling.
